Abstract: 811,442. Electrolytic recovery of non-ferrous alloy coatings. CLEVITE CORPORATION. Aug. 3, 1955 [Nov. 22, 1954], No. 22284/55. Class 41. A non-ferrous lead-containing copper base alloy coating is separated from a ferrous body by anodic dissolution in a strongly alkaline aqueous electrolyte containing an alkali metal cyanide and from 5 to 20 g./l. tartrate radical with an anode-electrolyte potential of not more than 0.8 volt, the alloy being cathodically deposited. The alloys may contain 1 to 40 per cent lead and as little as 55 per cent copper, while other non-ferrous metals such as tin and zinc may be present. Preferably the electrolyte contains the metal ions in the same proportion as in the alloy coating. The cathode may be of steel or copper and the scrap to be treated is contained in steel baskets which are moved to tumble the contents and assist in anodic dissolution of the alloy coating, the electrolyte being circulated by a pump through an external filter. To obtain the alloy in powder form, the bath is gently agitated by movement of the cathode so that a cathode current density of 30 to 80 or even up to 100 amps./sq. ft. may be used, the spongy deposit being readily scraped off the cathode and crushed. In the absence of agitation and with a cathode current density of up to 20 amps./sq. ft. an adherent cathode deposit is obtained.

Abstract: 630,493. Agricultural implements. VOGEL, F. Aug. 1, 1946, No 22976. Convention date, July 5, 1945. [Class 6(i)] A tractor-drawn, invertible plough is provided with hydraulic mechanism for raising the plough and for initiating the interchanging of the plough bodies. The plough comprises a main frame 1 secured to the tractor chassis by a pin 3 and lugs 2. A hydraulic cylinder 5 is pivoted to a pin 4 on the frame, the cylinder being supplied with fluid from the tractor through tubing 7. The piston 6 of the cylinder is connected to the shorter arm of, a bellcrank 9 pivoted at 10 on the main frame, the longer arm being attached by a chain 29 to a second bell-crank 28. The main beam 16,of the plough is rotatably mounted in a bearing 15 which is supported by a yoke 14 adjustably mounted on an L- shaped lever 11, 12, pivoted at 13 on the main frame. The yoke 14 is adjustable by the rotation of a crank 24 fixed to a threaded rod 23 which screws into a collar 22 supported by a pair of rods 17. The rods 17 are pivoted at their lower ends to a second L-shaped lever 18, 19 also mounted on the pivot 13, about which it may be rotated to vary the working depth of the tools. The bell-crank 28 is pivoted, at 27, on a bearing 26 and is connected to the bearing by a spring 30. The beam 16 is held in either of its operative positions by a spring-loaded bolt 33 engaging one of two notches 32 on a segment 31 rotatable with the beam. The bolt may be retracted by the downward movement of a wedge 36 slidable on the bearing 26 and connected at its lower end to a crank 39, 40. Mounted on the pivot 27 and movable with the bellcrank 28 is a lever 43 connected by a spring 42 to an arm 44 projecting from the plough beam 16. As the plough is raised by the cylinder 5, its weight is carried by the springs 30 and 42 which are thereby stretched. At the end of the raising movement, the crank 40 strikes the frame and releases the bolt 33. The beam 16 rotates under the action of the spring 42, but the recoil of the system permits the spring 42 to slacken so that the beam rotates through a full 180 degree arc after which the bolt 33 engages the other notch 32.
